At least one earthquake happens somewhere in the world every day.
On some days there are many more. A few cause great damage and loss of
life ; some are felt only as slight shudders of the ground ; many more are
so small that they cannot be felt at all. We know about them only because
they are shown on a seismograph - a delicate instrument which records
movements of the ground. It has a small needle which scratches a white
line on a strip of black paper, which is going round on a drum. When
everything is quite still the line is straight, but when the ground shakes
the line becomes wiggly. A severe earthquake, even though it is a long
way away, makes large wiggles on the line.
Many earthquakes happen under the sea and they often cause great
waves, called tsunamis. Tsunamis are taller than a house and they race
across the sea one after another at high speed. Ships in their path may be
wrecked and, when the waves reach land, there may be flooding and
enormous damage.
